Displacing the pump tubings

The displacement of the pump tubings is necessary to prevent the
mechanical wear of the pump tubings becoming too great.
If this activity is carried out regularly, the lifetime of the pump tubings
may exceed 6 months. The displacement can be carried out up to
5 times before the pump tubings become unusable.
To displace the pump tubings, carry out the following steps:
1 Open the door of the control unit housing.
2 Switch off the permeate pump (bring the permeate selector
switch into position 0).
3 Swing out the pump cassette. To do so, open the gripping
lever.
Subsequently, unlock the pump cassette by pressing on the
gripping lever and swing out the pump cassette.
